1, fiber identification
This is a very sensitive detector. When you will bend the fiber, the light radiation from the core. Optical fiber identification, and technical staff will be based on these optical detection in a single multi-core optical fiber distribution frame from the other fibers of the fiber. Optical Fiber Identifier can detect the direction of the light and does not affect the transmission. To make this work easier, usually modulated test signal at the sending end to the 270HZ, 1000Hz or 2000HZ, and injected into a specific fiber. The most important fiber wavelength 1310nm or 1550nm single-mode optical fiber identifier, fiber identifier can use the macro bend technology to determine the direction and power transmission optical fiber and optical fiber line testing.
2, the fault locator (fault trace)
Equipment based on laser diodes with visible light (red light) source, when injected into the light of the fiber if the fiber breakage, connector failure, bending, welding the poor quality of the failed fiber light launched into the fiber fault visualization positioning. The visual fault locator launched a continuous wave (CW) or pulsed mode. The typical frequency of 1Hz or 2Hz, but can also work in the kHz range. Under normal circumstances,China Optical Distribution Frame. Henan Zhang Jixiang feather information mill Siheung eighties in the last century. the output power of 0dBm (1mW) or less, the working distance of 2-5 km, and supports all common connector.
3, optical loss test equipment (also known as the optical multimeter Power Meter)
Measuring the loss of fiber link,Cat6a Keystone Jack and cat6a cabling are not much different than regular cat6 products in the end of the launch calibration light stabilizers, and read out the output power at the receiving end. Both devices are composed of optical loss tester. Light source and power meter, the synthesis of a set of instruments, often referred to as the optical loss test set (also called optical multimeter). When we measure the loss of a part of the operating test light at the sending end you need to use optical power meter to measure the receiving end, another loss, this can only be drawn in one direction.
Under normal circumstances, we need to measure the losses on both directions (because of the connection is lost, or is due to the asymmetry of the transmission loss). At this time, the technicians must exchange measuring equipment and other directions. However, when they separate more than 10 layers, or tens of kilometers, how to do it? Obviously, if two people have a light source and an optical power meter, then they can both sides of the simultaneous measurement of the use of advanced fiber-optic test suite for testing and certification, can be bi-directional dual wavelength testing, such as: “the CertiFiber Fluke DSP cable test series Free Trade Area of fiber optic test kits.
